BACKGROUND

Field

The present application relates to the fields of chemistry, biochemistry and medicine. More particularly, disclosed herein are bicyclopentane compounds. Also disclosed herein are methods of using bicyclopentane compounds as an analgesic.

Description

Nonsteroidal anti-inflammatory compounds, or NSAIDs, are an extremely useful group of small molecule drugs, typified by acetylsalicylic acid, ibuprofen and naproxen. These are often sold without prescription, and are variously used to treat pain, inflammation, and fever. However, NSAIDs can have undesirable side effects, including gastric upset and/or gastric bleeding.

Acetaminophen, also known as paracetamol or APAP, is also an effective pain reliever often sold over the counter (without prescription). Although it shares analgesic and antipyretic properties with NSAIDs, it has only weak anti-inflammatory properties, and is thus not an NSAID. Unlike many NSAIDs, acetaminophen does not cause gastric upset or bleeding in prescribed doses. Thus, it is an extremely useful drug for those wishing analgesia without adverse gastric side effects.

Acetaminophen has the structure:

Acetaminophen is often combined with other drugs for relief of symptoms of influenza and the common cold, among other indications. It is particularly useful in combination with opioid analgesics, where it exhibits synergistic analgesic properties and allows patients to achieve adequate pain relief with lower doses of opioids. The most widely prescribed drug in the United States is a combination of acetaminophen and hydrocodone, with over 130 million prescriptions in the year 2010. Other acetaminophen-opioid combinations, including combinations with oxycodone, are also widely prescribed.

Acetaminophen poisoning is the most common cause of acute liver failure in the Western world, and acetaminophen accounts for the most drug overdoses in the English-speaking world. Acetaminophen is metabolized to form N-acetyl-p-benzoquinoneimine (NAPQI), which depletes glutathione in the liver, and if the glutathione is sufficiently depleted, as is the case with an acetaminophen overdose, the NAPQI metabolite injures hepatocytes leading to acute liver failure and often death. The acetaminophen-opioid combination drugs are commonly implicated in such toxicity, for various reasons. First, patients might not recognize that the prescribed pain relievers contain acetaminophen, and may supplement with acetaminophen if pain relief is inadequate. Second, continued administration of opioids can lead to tolerance and the need for increased dosages to obtain a comparable opioid effect, and users or abusers of the combination drugs may exceed safe dosages of acetaminophen as a consequence.

This has led the U.S. FDA to seek reduced amounts of acetaminophen in the opioid combination drugs and has also led an FDA advisory panel to recommend banning such drugs all together. Although the acetaminophen-opioid drugs remain on the market, there is a strong need for a less toxic replacement without the same hepatotoxicity risks.

DETAILED DESCRIPTION Definitions

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. All patents, applications, published applications and other publications referenced herein are incorporated by reference in their entirety unless stated otherwise. In the event that there are a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

Whenever a group is described as being “optionally substituted” that group may be unsubstituted or substituted with one or more of the indicated substituents. Likewise, when a group is described as being “unsubstituted or substituted” if substituted, the substituent(s) may be selected from one or more the indicated substituents. If no substituents are indicated, it is meant that the indicated “optionally substituted” or “substituted” group may be substituted with one or more group(s) individually and independently selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl, heteroaryl, heterocyclyl, aryl(alkyl), heteroaryl(alkyl), heterocyclyl(alkyl), hydroxy, alkoxy, acyl, cyano, halogen, thiocarbonyl, O-carbamyl, N-carbamyl, O-thiocarbamyl, N-thiocarbamyl, C-amido, N-amido, S-sulfonamido, N-sulfonamido, C-carboxy, O-carboxy, isocyanato, thiocyanato, isothiocyanato, nitro, sulfenyl, sulfinyl, sulfonyl, haloalkyl, haloalkoxy, an amino, a mono-substituted amino group and a di-substituted amino group.

As used herein, “C_(a) to C_(b)” in which “a” and “b” are integers refer to the number of carbon atoms in a group. The indicated group can contain from “a” to “b”, inclusive, carbon atoms. Thus, for example, a “C₁ to C₄ alkyl” group refers to all alkyl groups having from 1 to 4 carbons, that is, CH₃—, CH₃CH₂—, CH₃CH₂CH₂—, (CH₃)₂CH—, CH₃CH₂CH₂CH₂—, CH₃CH₂CH(CH₃)— and (CH₃)₃C—. If no “a” and “b” are designated, the broadest range described in these definitions is to be assumed.

If two “R” groups are described as being “taken together” the R groups and the atoms they are attached to can form a cycloalkyl, cycloalkenyl, aryl, heteroaryl or heterocycle. For example, without limitation, if R^(a) and R^(b) of an NR^(a) R^(b) group are indicated to be “taken together,” it means that they are covalently bonded to one another to form a ring:

As used herein, the term “alkyl” refers to a fully saturated aliphatic hydrocarbon group. The alkyl moiety may be branched or straight chain. Examples of branched alkyl groups include, but are not limited to, iso-propyl, sec-butyl, t-butyl and the like. Examples of straight chain alkyl groups include, but are not limited to, methyl, ethyl, n-propyl, n-butyl, n-pentyl, n-hexyl, n-heptyl and the like. The alkyl group may have 1 to 30 carbon atoms (whenever it appears herein, a numerical range such as “1 to 30” refers to each integer in the given range; e.g., “1 to 30 carbon atoms” means that the alkyl group may consist of 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc., up to and including 30 carbon atoms, although the present definition also covers the occurrence of the term “alkyl” where no numerical range is designated). The alkyl group may also be a medium size alkyl having 1 to 12 carbon atoms. The alkyl group could also be a lower alkyl having 1 to 6 carbon atoms. An alkyl group may be substituted or unsubstituted.

The term “pharmaceutically acceptable salt” refers to a salt of a compound that does not cause significant irritation to an organism to which it is administered and does not abrogate the biological activity and properties of the compound. In some embodiments, the salt is an acid addition salt of the compound. Pharmaceutical salts can be obtained by reacting a compound with inorganic acids such as hydrohalic acid (e.g., hydrochloric acid or hydrobromic acid), a sulfuric acid, a nitric acid and a phosphoric acid (such as 2,3-dihydroxypropyl dihydrogen phosphate). Pharmaceutical salts can also be obtained by reacting a compound with an organic acid such as aliphatic or aromatic carboxylic or sulfonic acids, for example formic, acetic, succinic, lactic, malic, tartaric, citric, ascorbic, nicotinic, methanesulfonic, ethanesulfonic, p-toluensulfonic, trifluoroacetic, benzoic, salicylic, 2-oxopentanedioic, or naphthalenesulfonic acid. Pharmaceutical salts can also be obtained by reacting a compound with a base to form a salt such as an ammonium salt, an alkali metal salt, such as a sodium, a potassium or a lithium salt, an alkaline earth metal salt, such as a calcium or a magnesium salt, a salt of a carbonate, a salt of a bicarbonate, a salt of organic bases such as dicyclohexylamine, N-methyl-D-glucamine, tris(hydroxymethyl)methylamine, C₁-C₇ alkylamine, cyclohexylamine, triethanolamine, ethylenediamine, and salts with amino acids such as arginine and lysine. For compounds of Formulae (I) and/or (II), those skilled in the art understand that when a salt is formed by protonation of a nitrogen-based group (for example, NH₂), the nitrogen-based group can be associated with a positive charge (for example, NH₂ can become NH₃ ⁺) and the positive charge can be balanced by a negatively charged counterion (such as Cl⁻).

It is understood that, in any compound described herein having one or more chiral centers, if an absolute stereochemistry is not expressly indicated, then each center may independently be of R-configuration or S-configuration or a mixture thereof. Thus, the compounds provided herein may be enantiomerically pure, enantiomerically enriched, racemic mixture, diastereomerically pure, diastereomerically enriched, or a stereoisomeric mixture. In addition it is understood that, in any compound described herein having one or more double bond(s) generating geometrical isomers that can be defined as E or Z, each double bond may independently be E or Z a mixture thereof. Likewise, it is understood that, in any compound described, all tautomeric forms are also intended to be included.

It is to be understood that where compounds disclosed herein have unfilled valencies, then the valencies are to be filled with hydrogens or isotopes thereof, e.g., hydrogen-1 (protium) and hydrogen-2 (deuterium).

It is understood that the compounds described herein can be labeled isotopically. Substitution with isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, such as, for example, increased in vivo half-life or reduced dosage requirements. Each chemical element as represented in a compound structure may include any isotope of said element. For example, in a compound structure a hydrogen atom may be explicitly disclosed or understood to be present in the compound. At any position of the compound that a hydrogen atom may be present, the hydrogen atom can be any isotope of hydrogen, including but not limited to hydrogen-1 (protium) and hydrogen-2 (deuterium). Thus, reference herein to a compound encompasses all potential isotopic forms unless the context clearly dictates otherwise.

It is understood that the methods and combinations described herein include crystalline forms (also known as polymorphs, which include the different crystal packing arrangements of the same elemental composition of a compound), amorphous phases, salts, solvates, and hydrates. In some embodiments, the compounds described herein exist in solvated forms with pharmaceutically acceptable solvents such as water, ethanol, or the like. In other embodiments, the compounds described herein exist in unsolvated form. Solvates contain either stoichiometric or non-stoichiometric amounts of a solvent, and may be formed during the process of crystallization with pharmaceutically acceptable solvents such as water, ethanol, or the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol. In addition, the compounds provided herein can exist in unsolvated as well as solvated forms.

Examples of compounds of Formula (II) include, but are not limited to:

or a pharmaceutically acceptable salt of the foregoing. Methods

The various compounds contemplated herein can be synthesized from known starting materials by various routes. Some suitable routes are illustrated in Schemes 1 and 2, with syntheses described in more detail in the following description and Examples.

As shown in Scheme 1, compounds of Formula (I) can be prepared starting from a compound of Formula (A). The reaction of a compound of Formula (A) with a Grignard reagent followed by trapping with an electrophile such as carbon dioxide leads to a carboxylic acid compound. The carboxylic acid compound can be transformed to a carboxamide through an amide bond formation reaction with ammonia as the amine source. The carboxamide compound can be reduced using standard reducing reagents such as lithium aluminum hydride to give a primary amine. A second amide bond formation reaction with various reagents such as carboxylic acids, acid chlorides, or acid anhydrides leads to compounds of Formula (I).

For example, the reaction of [1.1.1]propellane with tert-butylmagnesium chloride followed by quenching the reaction with carbon dioxide gives 3-(tert-butyl)bicyclo[1.1.1]pentane-1-carboxylic acid. The conversion of 3-(tert-butyl)bicyclo[1.1.1]pentane-1-carboxylic acid to 3-(tert-butyl)bicyclo[1.1.1]pentane-1-carboxamide can be carried out using various amide bond formation reactions, for example by forming an acid chloride using reagents such as thionyl chloride or oxalyl chloride and then treating the formed 3-(tert-butyl)bicyclo[1.1.1]pentane-1-carbonyl chloride with ammonia. The reduction of 3-(tert-butyl)bicyclo[1.1.1]pentane-1-carboxamide can be carried out using such reagents as lithium aluminum hydride to give (3-(tert-butyl)bicyclo[1.1.1]pentan-1-yl)methanamine. The treatment of (3-(tert-butyl)bicyclo[1.1.1]pentan-1-yl)methanamine with reagents such as acetic anhydride or acetyl chloride gives N-((3-(tert-butyl)bicyclo[1.1.1]pentan-1-yl)methyl)acetamide.

Compounds of Formula (I) can also be prepared starting from a compound of Formula (A) via the route shown in Scheme 2. Compound of Formula (A) can be reacted with methyl lithium and R³X in ether, wherein X is a suitable leaving group (for example, a halogen). A carboxylic acid moiety can be formed using t-butyl lithium and carbon dioxide. The carboxylic acid compound can be transformed and form a protected amine via a Curtius rearrangement using an azide, a reagent(s) that can provide the protecting group and a base, such as diphenylphosphoryl azide (DPPA), t-BuOH and triethyl amine, respectively. The protecting group can be removed using methods known to those skilled in the art, such as an acid. If desired and/or needed, the carboxylic acid compound can be converted to a carboxylic acid chloride before forming the protected amine.

Salts can be formed using methods known to those skilled in the art and described herein, for example, reacting an amine with a suitable acid (such as HCl).

Pharmaceutical Compositions

Some embodiments described herein relate to a pharmaceutical composition, that can include an effective amount of one or more compounds described herein (e.g., a compound of Formulae (I) and/or (II), or a pharmaceutically acceptable salt thereof) and a pharmaceutically acceptable carrier, diluent, excipient or combination thereof.

The term “pharmaceutical composition” refers to a mixture of one or more compounds disclosed herein with other chemical components, such as diluents or carriers. The pharmaceutical composition facilitates administration of the compound to an organism. Pharmaceutical compositions can also be obtained by reacting compounds with inorganic or organic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, and salicylic acid. Pharmaceutical compositions will generally be tailored to the specific intended route of administration.

The term “physiologically acceptable” defines a carrier, diluent or excipient that does not abrogate the biological activity and properties of the compound nor cause appreciable damage or injury to an animal to which delivery of the composition is intended.

As used herein, a “carrier” refers to a compound that facilitates the incorporation of a compound into cells or tissues. For example, without limitation, dimethyl sulfoxide (DMSO) is a commonly utilized carrier that facilitates the uptake of many organic compounds into cells or tissues of a subject.

As used herein, a “diluent” refers to an ingredient in a pharmaceutical composition that lacks appreciable pharmacological activity but may be pharmaceutically necessary or desirable. For example, a diluent may be used to increase the bulk of a potent drug whose mass is too small for manufacture and/or administration. It may also be a liquid for the dissolution of a drug to be administered by injection, ingestion or inhalation. A common form of diluent in the art is a buffered aqueous solution such as, without limitation, phosphate buffered saline that mimics the pH and isotonicity of human blood.

As used herein, an “excipient” refers to an essentially inert substance that is added to a pharmaceutical composition to provide, without limitation, bulk, consistency, stability, binding ability, lubrication, disintegrating ability etc., to the composition. A “diluent” is a type of excipient.

The pharmaceutical compositions described herein can be administered to a human patient per se, or in pharmaceutical compositions where they are mixed with other active ingredients, as in combination therapy, or carriers, diluents, excipients or combinations thereof. Proper formulation is dependent upon the route of administration chosen. Techniques for formulation and administration of the compounds described herein are known to those skilled in the art.

The pharmaceutical compositions disclosed herein may be manufactured in a manner that is itself known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or tableting processes. Additionally, the active ingredients are contained in an amount effective to achieve its intended purpose. Many of the compounds used in the pharmaceutical combinations disclosed herein may be provided as salts with pharmaceutically compatible counterions.

Multiple techniques of administering a compound exist in the art including, but not limited to, oral, rectal, pulmonary, topical, aerosol, injection, infusion and parenteral delivery, including intramuscular, subcutaneous, intravenous, intramedullary injections, intrathecal, direct intraventricular, intraperitoneal, intranasal and intraocular injections.

One may also administer the compound in a local rather than systemic manner, for example, via injection or implantation of the compound directly into the affected area, often in a depot or sustained release formulation. Furthermore, one may administer the compound in a targeted drug delivery system, for example, in a liposome coated with a tissue-specific antibody. The liposomes will be targeted to and taken up selectively by the organ. For example, intranasal or pulmonary delivery to target a respiratory infection may be desirable.

The compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active ingredient. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. The pack or dispenser may also be accompanied with a notice associated with the container in form prescribed by a governmental agency regulating the manufacture, use, or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the drug for human or veterinary administration. Such notice, for example, may be the labeling approved by the U.S. Food and Drug Administration for prescription drugs, or the approved product insert. Compositions that can include a compound described herein formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labeled for treatment of an indicated condition.

Such administration can, in some circumstances, substitute for or significantly reduce the need for administration of an opiate. Some methods described herein can include intravenous administration to a subject in need thereof, for example, to a subject to manage post-operative or other acute or chronic pain, in either a bolus dose or by infusion over minutes, hours, or days. Other methods described herein can include oral, intravenous and/or intraperitoneal administration to a subject in need thereof, for example, to a subject to manage post-operative or other acute or chronic pain.

Other embodiments described herein relate to a method for selecting a therapy for managing or treating pain in a subject in need thereof, that can include evaluating whether the subject is at risk for hepatic toxicity from pain therapy, and selecting therapy that includes a compound of Formulae (I) and/or (II), or a pharmaceutically acceptable salt thereof, to reduce or eliminate such risk. The method can further include providing the selected therapy that includes a compound of Formulae (I) and/or (II), or a pharmaceutically acceptable salt thereof, to the subject. In some embodiments, a compound of Formulae (I) and/or (II), or a pharmaceutically acceptable salt thereof, can be of significant benefit in pain management in hospitals or other care facilities (for example, a nursing home).

As used herein, the terms “prevent” and “preventing,” mean a subject does not experience and/or develop pain and/or fever, or the severity of the pain and/or fever is less compared to the severity of the pain and/or fever if the subject has not been administered/received the compound. Examples of forms of prevention include prophylactic administration to a subject who is going to undergo surgery.

As used herein, the terms “treat,” “treating,” “treatment,” “therapeutic,” and “therapy” do not necessarily mean total cure or abolition of the disease or condition. Any alleviation of any undesired signs or symptoms of a disease or condition, to any extent can be considered treatment and/or therapy. Furthermore, treatment may include acts that may worsen the subject's overall feeling of well-being or appearance.

The terms “therapeutically effective amount” and “effective amount” are used to indicate an amount of an active compound, or pharmaceutical agent, that elicits the biological or medicinal response indicated. For example, a therapeutically effective amount of compound can be the amount needed to prevent, alleviate or ameliorate symptoms of disease or prolong the survival of the subject being treated This response may occur in a tissue, system, animal or human and includes alleviation of the signs or symptoms of the disease being treated. Determination of an effective amount is well within the capability of those skilled in the art, in view of the disclosure provided herein. The therapeutically effective amount of the compounds disclosed herein required as a dose will depend on the route of administration, the type of animal, including human, being treated, and the physical characteristics of the specific animal under consideration. The dose can be tailored to achieve a desired effect, but will depend on such factors as weight, diet, concurrent medication and other factors which those skilled in the medical arts will recognize.

The amount of the compound, or an active salt or derivative thereof, required for use in treatment will vary not only with the particular salt selected but also with the route of administration, the nature of the condition being treated and the age and condition of the patient and will be ultimately at the discretion of the attendant physician or clinician. In cases of administration of a pharmaceutically acceptable salt, dosages may be calculated as the free base. As will be understood by those of skill in the art, in certain situations it may be necessary to administer the compounds disclosed herein in amounts that exceed, or even far exceed, the above-stated, preferred dosage range in order to effectively and aggressively treat particularly aggressive diseases or conditions.

In general, however, a suitable dose will often be in the range of from about 0.15 mg/kg to about 100 mg/kg. For example, a suitable dose may be in the range from about 1 mg/kg to about 75 mg/kg of body weight per day, such as about 0.75 mg/kg to about 50 mg/kg of body weight of the recipient per day, about 1 mg/kg to 90 mg/kg of body weight of the recipient per day, or about 10 mg/kg to about 60 mg/kg of body weight of the recipient per day.

The compound may be administered in unit dosage form; for example, containing 1 to 2000 mg, 10 to 1000 mg or 5 to 500 mg of active ingredient per unit dosage form.

The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day. The sub-dose itself may be further divided, e.g., into a number of discrete loosely spaced administrations.

As will be readily apparent to one skilled in the art, the useful in vivo dosage to be administered and the particular mode of administration will vary depending upon the age, weight, the severity of the affliction, and mammalian species treated, the particular compounds employed, and the specific use for which these compounds are employed. The determination of effective dosage levels, that is the dosage levels necessary to achieve the desired result, can be accomplished by one skilled in the art using routine methods, for example, human clinical trials, in vivo studies and in vitro studies. For example, useful dosages of compounds of Formulae (I) and/or (II), or pharmaceutically acceptable salts thereof, can be determined by comparing their in vitro activity, and in vivo activity in animal models. Such comparison can be done against an established analgesic drug, such as acetaminophen.

Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the modulating effects, or minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from in vivo and/or in vitro data. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations. Dosage intervals can also be determined using MEC value. Compositions should be administered using a regimen which maintains plasma levels above the MEC for 10-90% of the time, preferably between 30-90% and most preferably between 50-90%. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.

It should be noted that the attending physician would know how to and when to terminate, interrupt, or adjust administration due to toxicity or organ dysfunctions. Conversely, the attending physician would also know to adjust treatment to higher levels if the clinical response were not adequate (precluding toxicity). The magnitude of an administrated dose in the management of the disorder of interest will vary with the severity of the condition to be treated and to the route of administration. The severity of the condition may, for example, be evaluated, in part, by standard prognostic evaluation methods. Further, the dose and perhaps dose frequency, will also vary according to the age, body weight, and response of the individual patient. A program comparable to that discussed above may be used in veterinary medicine.

Compounds disclosed herein can be evaluated for efficacy and toxicity using known methods. For example, the toxicology of a particular compound, or of a subset of the compounds, sharing certain chemical moieties, may be established by determining in vitro toxicity towards a cell line, such as a mammalian, and preferably human, cell line. The results of such studies are often predictive of toxicity in animals, such as mammals, or more specifically, humans. Alternatively, the toxicity of particular compounds in an animal model, such as mice, rats, rabbits, dogs or monkeys, may be determined using known methods. The efficacy of a particular compound may be established using several recognized methods, such as in vitro methods, animal models, or human clinical trials. When selecting a model to determine efficacy, the skilled artisan can be guided by the state of the art to choose an appropriate model, dose, route of administration and/or regime.

For some compounds, the foregoing syntheses are exemplary and can be used as a starting point to prepare additional compounds of Formula (I). Examples of additional compounds of Formula (I) are shown below. These compounds can be prepared in various ways, including those synthetic schemes shown and described herein. Those skilled in the art will be able to recognize modifications of the disclosed syntheses and to devise routes based on the disclosures herein; all such modifications and alternate.

Example A Formalin Paw Test

One test compound or the vehicle was administered to each mouse in each test group (8 mice per group). Non-fasted male ICR mice weighing 23±3 g were used. Test compounds were administered at a concentration of 3 mg/kg, 10 mg/kg, 15 mg/kg, 30 mg/kg, 60 mg/kg, 100 mg/kg, 200 mg/kg or 300 mg/kg; morphine was administered at a concentration of 5 mg/kg; and acetaminophen was administered at a concentration of 200 mg/kg. The control group received the vehicle (5% DMSO/40% PEG400/20% HPbCD/Saline). After 30 or 60 minutes, a 2% formalin solution (0.02 mL) was injected into one hind paw (sub-plantar) of each mouse. Responses were measured every 5 minutes after the formalin injection for 35 minutes.

Exemplary results are provided in Tables A and B. As shown in Tables A and B, compounds of Formulae (I) and (II) significantly decreased the pain response in both the early/acute phase (0-10 minutes) and the late/tonic phase (10-35 minutes). The results in Table A are for oral administration; the results in Table B are for intraperitoneal administration. In Tables A and B, ‘A’ designates <70 licks/sec, ‘B’ designates ≥70 licks/sec and <165 licks/sec, and ‘C’ designates ≥165 licks/sec.

Example B Glutathione Conjugation Assay

An incubation mixture consisting of 5 μL of 10 mM test compound in DMSO (5 μL of DMSO for negative control; 5 μL of 10 mM acetaminophen in DMSO for positive control), 5 μL of 0.1 μM glutathione 25 mM EDTA in water, 50 μL of 100 mM MgCl2 in water, 50 μL of 20 mg/mL pooled human liver microsomes (P-450 content: ˜0.5 nmol/mg protein), and 340 μL of 100 mM potassium phosphate buffer (pH 7.4) is preincubated at 37° C. for 10 mins. The reaction is initiated by the addition of 50 μL of 100 mM NADPH solution. The final incubation volume is 0.5 mL. The incubation mixture contains 100 μM test compound or acetaminophen (positive control), 1 mM glutathione, and 1 μM P450. After 60 mins incubation at 37° C., 1 mL of chilled acetonitrile is added to stop the reaction. After the addition of acetonitrile, the sample is vortexed and centrifuged. The supernatant is collected, concentrated in TurboVap under N₂ (10 psi) at 30° C. for 35 mins, and transferred to a 96-well plate. The plate is capped and centrifuged. The supernatant is injected for LC-MS/MS analysis.

As described herein, acetaminophen can form the reactive metabolite, N-acetyl-p-benzoquinone imine (NAPQI), which is linked to liver toxicity. Acetaminophen is metabolically activated by cytochrome P450 enzymes to form NAPQI, and NAPQI depletes endogenous glutathione (GSH). The depletion of endogenous glutathione leaves cells vulnerable to oxidative damage. The formation of NAPQI is the result of the phenol or aniline ring of acetaminophen.

Unlike acetaminophen, compound of Formulae (I) and/or (II) do not include a phenol or aniline ring and it is impossible to connect a substituent through a double bond (such as a carbonyl or imine group) at either end of bicyclo[1.1.1]pentane (i.e., at the 1 or 3 positions). As a result, one skilled in the art would not expect compounds of Formulae (I) and/or (II) to form the reactive metabolite NAPQI. A 129 neutral loss scan can be used to search or detect the formation of glutathione conjugates of reactive metabolites.

Although the foregoing has been described in some detail by way of illustrations and examples for purposes of clarity and understanding, it will be understood by those of skill in the art that numerous and various modifications can be made without departing from the spirit of the present disclosure. Therefore, it should be clearly understood that the forms disclosed herein are illustrative only and are not intended to limit the scope of the present disclosure, but rather to also cover all modification and alternatives coming with the true scope and spirit of the invention.
